Seems to work fine so far. Thanks. It's a HUGE relief, man!
But the particle stuck at 0,0,0 still remains.

don't see any stuck at 0,0,0...
if you have an example, I coul test it...

I can't repro this for sure. If I change RandomSeed from 0 to 1 in Sparkle, then it's gone. It also has to do with Percentage. When RandomSeed =0, then any change in Percentage makes it dosappear and appear again.

What really alerts me is that my ufo crash1.wz4 (viewtopic.php?f=43&t=1115) is crashing wzCE

is this the particles on the left that you spoke ?

For the ufo, I can't reproduce any crash... tested on x86 and x64

If you have a crashing file, send me. Is is easier to debug for me because it directly jump into the code and to the crashing instructions and with the debugger I can examine variables content.

The bug related to sparcle that I fixed, affected also trails and morphstream (I also fixed that) in fact most of particle modifiers when they in combination with exploder. I saw that your ufo file use woble as particle modifiers, so maybe it can be the affected too, but for now didn't experienced crash with it...

OK. I will get back to that issue this evening and try to repro this bug from scratch. This issue has always been tricky and depended on whether I had initialized (showed) splined particles before, or copied the problem stack to a new wz4 file. I will try to create all possible combinations from scratch and send you my thoughts.

is this the particles on the left that you spoke ?

In fact, you may not use view the from camera. Show from the Spline op.
The white particle(s) appears right at 0,0,0.

sorry, I don't see anything
I tried to change all values, randomseed, pourcentage, particles counts, etc...

Which videocard do you use?

nvidia gtx
I'll test it on an old ati later.

I have 2 setups: one with Nvidia GTX590 and the other with Nvidia GT630. The setup with Nvidia GT630 has the bug with ufo_crash1.wz4 I reported yesterday and the bug with particles at 0,0,0. I will test it on GTX590 later this week.

And I have just remembered that the bug tended to occur less often if I turned on XP Sp3 compatibility mode for wz4. Now I can't use that mode on my newer hardware (the one with GTX590) - wz crashes on me at start. Maybe it's because of windows7 updates... Don't know for sure...

I'm testing Sparkle now. Everything is fine until I set lifetime of SplinedParticles more than 1. Then the white dot at 0,0,0 appears. It seems that Sparkle doesn't know what to do with redundant particle life span and sends the particles to render outside the spline.

can you take a screenshot, There is nothing for me :p

Here.

wtf, i get nothing even on the ati card lol.
